EL luminescent dash and side counsel dimmer

My 97 has the mirror controls at the top. My relocated retarder handle is where your brightness knob is. 

I wonder if the 97 is capable of being lit?  Just did not have an inverted power supply wired to it?  Maybe too dark?  Another mystery.

I have a spare dash setup with the power supplies on them.  I think.  My guru buddy semi retired.  Half to bug him to look.

The selected media item is not currently available. The selected media item is not currently available.

Someone had posted this earlier

Looks like an earlier version without the left/retarder panel illumination

Might be inverted power?

Tommy,
  Thanks for posting that inverter diagram. Didn't have it.

Not off the inverter in the coach.  Something in the dash might be changing 12 volt to 110?  There are round things attached to the back of the electro dash panels

Read the link in reply #44 12 volt input 100 volt vac 600 hz. output.

Thanks.  Had not opened the link.  Seems I was somewhat correct

The early 98 diagram shows a circuit to the side panel.

Have talked with several of you guys about the EL dash problem and got good information but since I am a little slow on the uptake and still didn't understand how to fix the problem I called James at Xtreme,  This is what I understood after talking with him and he is one of the people who used to build the EL dash at Foretravel. 

So the dash is like a sandwich you have the following layers
1 Aluminum Plate
2 insulation film
3 EL Wiring
4 top insulation film (in my case its black)

He explained the problem as the bottom insulation has been disturbed(gone bad) and is allowing the EL wiring to contact the Aluminum and thus causing the spark/arc and will eventually short out the panel.  He said the #2,3,4 are made together like a heavy duty film and are one piece and have been glued to the Aluminum. 

THE FIX:
-If its in the dash you will have to remove the panel that is bad or having problems.
-In my case its to the left of the dash (where my Retarder joystick is) so I'm lucky and only have to remove 6 screws and lift the plate
up to get at my problem area.  I think I will be able to leave everything connected to attempt the fix.
-once you have access to the panel edge you should be able to use an exacto knife or blade to separate the heavy duty film from the aluminum.  Make sure you are seeing aluminum when you separate.  He recommended separating around the entire edge and doing the whole panel but I am going to just work on the area of my problem 1st.  He said the film is pretty heavy duty and should not be a problem to separate from the aluminum.  After removal use Liquid Electric Tape (My local hardware store had some or Lowes, Autozone) to coat the area to re insulate it and let it dry. 

My understanding is that the purpose is to re insulate the area under the membrane so it will stop arcing.

From the side view I could see faintly where the aluminum stopped and the membrane started.

My understanding as well.

Liquid electrical tape. Didn't know there was such a thing.

I have been wondering what that resister switch was beside the retarder joy switch. Now I will try and find out why it doesn't work.
